Adding Hidden Text to Formulas
Imagine
you have a formula like: =$2018+$1056-4*$120. When you initially wrote it you
knew what each number represented, but you come back later and can't remember.
Add a hidden note to your formula by using the N() formula i.e.
=$2018+$1056-4*$120+N("My Wage+Bonus-4 weekly loan repayments"). The N()
function will convert text to zero.
